Definitions

  • This invention relates generally to the control of a high pressure fluid and, more particularly, to valves used to achieve pressure drops in fluid flow lines.
  • valve installation that includes, as elements thereof, structure defining a flow passage, a seat in the passage and a plug movable toward and away from the seat.
  • Such an installation has been modified by provision of tuned, blind holes in surfaces of one or more of the above elements. The holes face downstream in t ' hat they are disposed angularly in the intended direction of flow through the passage.
  • Fig. 1 the improvements of the present invention have been shown in a test valve having a body 10 provided with a through passage 12.
  • body 10 where passage 12 changes direction, there is a bridge 14 that receives a seat ring 16.
  • Seat 16 is shaped to receive the tapered end of a plug 18 when the flow through passage 12 is to be interrupted.
  • Plug 18 is on the end of a stem 20 and the stem projects from body 10 through a bonnet 22.
  • Bonnet 22 is held in place by a bonnet flange 24 and cap screws 26.
  • a seat-retaining cage ' 28 is fitted between bonnet 22 and seat ring 16.
  • body 10 has inlet and outlet flanges 30, 32 adapted for attachment to other flanges or elements in a fluid flow line.
  • Adjacent flanges 30, 32, passage 12 has straight lengths fitted with inner sleeves 36.
  • Each sleeve 36 has a plurality of angularly disposed, round holes 38 that present elliptical apertures in its inner surface. As illustrated, holes 38 face downstream, i.e., are disposed angularly in the intended direction of flow through passage 12. The manner in which each hole is sized or "tuned" to null sound waves over a narrow band of frequencies is described below.
  • Plug 18 has holes 40 drilled inwardly and downwardly toward its axis.
  • Seat 16 has holes 42 drilled inwardly and downwardly toward its center alternating with holes 43 drilled downwardly and outwardly from the bevelled seat.
  • Cage 28 has spaced, circumferentially disposed webs 44 and each web has staggered rows of holes 46, 48 drilled into its opposed, rounded edges.
  • pressurized fluid flows into valve 10 at flange 30 and through the orifice in ring 16 to flange 32. In doing so, the fluid passes over the apertured surfaces of the sleeves 36, ring 16, plug 18 and cage 28.
  • the modified cage shown at 49 in Fig. 3 includes a plurality of identical discs 50 stacked between a lower, end plate 52 and an upper, end plate 54.
  • Plate 52 engages seat ring 55 and the upper side of plate 54 has an annular lip that fits in a seat on the bonnet.
  • Plate 54 has vent ports 56 for balancing the forces on plug 57 when it is in an open position.
  • Each disc 50 has dependent outer and inner legs 58, 60 and an annular ledge 62 on its upper side. The heights of legs 58, 60 and ledges 62 are such as to define an annular duct between adjacent discs and an annular screen 64 is located in each duct.
  • a plurality of radially disposed, inwardly and downwardly sloped, tuned holes 66 are drilled into the outer edge of each ledge 62.
  • the blind holes are tuned according to the wavelength of the predominant tone in the spectrum of noise generated in an unmodified valve.
  • a valve can be installed in an air test line, with a microphone nearby, and placed in operation at various flow rates while the generated noise is charted.
  • After noting the frequency of the predominant tone using a frequency spectral analyzer (Nicolet 446A FFT) and a digital plotter, blind holes are provided in the surfaces of one or more of the elements in the valve.
  • the length of the holes is a fourth of the wavelength (X/4) of the predominant tone.
  • the predominant tone has a frequency of 8250 hertz (Hz).
  • the blind holes have a depth of 0.410 inch. Adjacent holes should have their edges spaced at 1.5-1.75 times the hole diameter and the diameter should not exceed a half of the depth. To achieve the maximum effect, the holes are as large and spaced as frequently as is practicable. In the latter respect, if the holes are too small, cross modes are produced and, if too large, sound waves are reflected at angles greater than desired.
  • the spectrum of noise generated by a valve has several peak frequencies. It will occur to those skilled in the art that further reductions in noise could be achieved by tuning some of the holes to one or more of those frequencies and the rest to the predominant tone. Such a modification has been shown in Fig. 4 where the tuned holes 38a, 38b, 38c have different depths. Those skilled in the art will recognize that sectional sleeves 36 could be provided with holes of different depths in different sections.
  • Tuned holes 38' would be cast in body 10', using a sand core with projecting spikes, and could, of course, vary in depth as shown in Fig. 4.
  • an unmodified globe valve 70 has extensions 72, 74 attached to inlet and outlet flanges 76, 78.
  • Each extension includes a short length of pipe between a pair of flanges with which it is attached to valve 70 and a similar flange in a fluid flow line 79.
  • the flow passage is defined not only by the structure of valve 70 but also by extensions 72, 74 and adjacent lengths of flow line 79.
  • each extension contains an imperforate liner 80 and a sleeve 36" provided with holes 38" disposed angularly in the direction of flow through the valve installation.
  • liners 80 and sleeves 36" are within extensions 72, 74, as shown by broken lines in Fig. 6. It will be apparent on inspection that liners 80 could be eliminated in favor of a tight fit between sleeves 36" and the bores of the extensions.
  • the data show that the best results have been obtained, in all of the tests, with 0 blind holes disposed at an angle of about 60 . Worthwhile reductions in noise levels have been achieved with o the blind holes disposed at angles between about 30 and o approaching 90 .
